Question

What is the value of the function f(x) = 2x – 5 when x = 22? 17 39 49 105

Answer 1

substitute 22 for x
2(22)-5
44-5
39

Answer 2

Take the original equation, substitute x for 22, and use PEMDAS to solve.

f(x) = 2x - 5
f(x) = 2(22) - 5
f(x) = 44 - 5
f(x) = 39

Your final answer will be 39.
